This question is self explanatory if you know how to use JMockit: How do I mock a method that has generics on it? I want to mock this method: public T save(T entity) but it always throws an exception like this:

mockit.RealMethodNotFoundForMockException: Corresponding real methods not found for the following mocks: Object save(Object)     at mockit.internal.RedefinitionEngine.modifyRealClass(RedefinitionEngine.java:130)     at mockit.internal.RedefinitionEngine.modifyRealClass(RedefinitionEngine.java:88)     at mockit.internal.RedefinitionEngine.redefineMethods(RedefinitionEngine.java:72)     at mockit.Mockit.setUpMocks(Mockit.java:197)     at com.mytest.MyTest.setUp(AdminManagerImplTest.java:83)

  1. it does work for me, example

     package a;  import junit.framework.TestCase; import mockit.Mockit;  public class JMockitCoreExampleTest extends TestCase {      public class MockMe {         public T save(T t) {             return null;         }     }      public void testDoOperationAbc() {         Mockit.redefineMethods(MockMe.class, SayThatYouMockMe.class);                 MockMe mock = new MockMe();         System.out.println(mock.save('aaa'));     }      public static class SayThatYouMockMe {         public T save(T t) {             return t;         }     } }

    output

     Loaded external tool: mockit.integration.junit3.JUnitTestCaseDecorator Loaded external tool: mockit.integration.junit4.JUnit4ClassRunnerDecorator aaa

    maybe you are mocking hibernate’s save method? if so try using jmockit’s hibernate3emul.jar
